This Chocolate Oreo Cookies & Cream Cake yields a tender and delicious cake, sandwiched between thin creamy layers of white chocolate ganache and cookie crumbs.

My little one recently turned 6 years old and requested that I make him an Oreo cookie cake for his birthday. 

Typically, I don't keep Oreos in my pantry, since I like making my cookies from scratch, but this time, I obliged for the birthday boy.

Why you'll love this recipe

This recipe produces a tender and delicious chocolate cake.

The cream filling isn't too sweet, despite using white chocolate and Oreo cookies.

It makes a 2 layered (or 4 thin-layered) 6" cake, perfect for small servings.

You can make the cake with all-purpose flour; no need for cake flour in this cake.

There's no butter in the cake, so no need to soften butter at room temperature!

Tools and equipment you'll need

• 2 round 6" cake pans: I prefer aluminum pans as they conduct heat more evenly
• parchment paper: for lining the cake pans
• offset spatula: for spreading the cream easily in between layers and on the sides of the cake; if you don't have one, you can use a butter knife
• cake turntable: not absolutely necessary, but will make it easier to frost the cake
• cake board: a wrapped piece of round cardboard that holds the cake; not absolutely necessary

Ingredients

For the chocolate cake:

• all-purpose flour: regular flour will work here; no need for cake/pastry flour
• baking soda: reacts with the acid in the buttermilk to produce leavening
• baking powder: another leavening agent that helps provide lift to the cake
• sea salt: balances out the flavour in the cake
• granulated sugar: adds sweetness to the cake
• cocoa powder: you can use natural or Dutch-process
• avocado oil: or any light neutral vegetable oil
• buttermilk: if you don't have buttermilk, just use whole milk and add 1 tablespoon of white vinegar or lemon juice and give it a mix
• hot water: boiling water
• vanilla extract: use a high-quality vanilla extract for the best flavour
• eggs: adds structure and leavening to the cake

For the cream filling (ganache):

• white chocolate: you can use any type of white chocolate
• heavy whipping cream: with at least 36% milkfat (MF)
• vanilla extract: use a high-quality vanilla extract for the best flavour
• salted butter: I use a salted butter to help balance out the sweetness in the white chocolate; if you use unsalted butter, you can add ⅛ teaspoon sea salt
• powdered sugar: also known as icing sugar, helps to stiffen up the cream filling a touch
• Oreo cookies: you can use any cream sandwich-style cookie

How to make it

Make the cake:

Prepare 2 round 6" pans by lining the bottoms with parchment paper. Set aside.

Preheat oven to 325F. 

In a stand mixer bowl fitted with a paddle attachment, sift together the all-purpose flour, baking soda, baking powder, sea salt, sugar and cocoa powder.

Using a measuring cup, combine the avocado oil, buttermilk, boiling water and vanilla extract. Give it a stir to combine.

Gradually pour the liquid mixture into the dry ingredients, while the mixer is running on low. Increase the speed to beat the ingredients together, for about 30 seconds until smooth (don't overbeat).

Give the bowl a scrape and with the mixer on low, add 1 egg at at a time, and beat again until smooth, another 30-60 seconds. 

Divide the cake batter evenly into 2 round 6" pans.

Give the pans a tap to release any trapped air bubbles.

Bake the cakes at 325F for 30-35 minutes, or until a toothpick inserted comes out clean or with the slightest crumbs clinging to it.

Remove from the oven and cool on a wire rack for 15 minutes, before removing the cakes from the pans.

Make the cream filling (ganache):

Place the chopped white chocolate into a heat-safe bowl or stand mixer bowl.

Heat the heavy cream in a small saucepan over medium heat, until scalding hot.

Pour the hot cream over the white chocolate and let it sit for a few minutes. 

Give the chocolate and cream (ganache) a stir until completed melted. Stir in the salt and vanilla extract. 

Let the chocolate mixture cool to room temperature, or chill in the fridge.

Once the ganache has cooled, use the whisk attachment to whip it up over low speed.

Gradually increase the speed, and add in the butter in 1 tablespoon increments.

Once all the butter has been added, add in the powdered sugar and whip on high speed until the ganache is light and fluffy. 

Fold in the cookie crumbs until incorporated into the cream.

If the temperature is warm, you may need to chill the ganache from time to time to keep it from being too runny.

Store in the fridge until ready to use.

If the ganache is too cold, you may need to whip it up a little prior to using.

Assemble:

If you want to make 4 layers, you can slice each cake in half equatorially. Otherwise, you can leave it as 2 layers.

Add a little dollop of cream on a cake board (to secure the cake).

Place the cake on the cake board.

Add about ½ C of cream to the cake and use an offset spatula to spread an even layer towards the edges.

Place another cake on top and repeat.

Taking the remaining cream, spread a thin layer over the exterior (this is the crumb coat).

Place the cake in the fridge to chill for about 10-15 minutes.

Spread another layer of cream over the surface of the cake to smooth it out. 

Decorate however you like and keep in the fridge until ready to serve.

How to serve

About 30 minutes prior to serving, take the cake out of the fridge.

Slice the cake with a warmed, clean sharp knife.

How to store

Cover and store the cake in the fridge for up to 3 days.

Alternatively, you can freeze individually wrapped cake slices for up to 1 month.

FAQs & troubleshooting

My ganache is melting/too runny/too cold

If the temperature is too warm, you may need to chill the ganache from time to time to keep it from being too runny.

If the ganache is too cold, you may need to whip it up a little prior to using.

How do I get even cake layers?

If the cake has domed a little, you can use a serrated knife to trim off the tops to make them even.

How do I make the cake into 4 layers?

Use a sharp serrated knife to slice each cake in half equatorially.

Can I make the cake in advance?

Yes, you can make the cake ahead of time and freeze it.

Just individually wrap each cake with plastic, and then again with aluminum foil before storing in a freezer bag.

1-2 days before you want to assemble the cake, defrost the cake in the fridge.

How do you cut clean slices of cake?

Have a glass of warm-hot water close by and dip your knife into it.

Clean the knife with a dry cloth or paper towel, and then slice the cake.

Repeat in between slices.

Do I need a cake turntable?

A cake turntable will make spreading the frosting/cream easier, but it is not completely necessary.
